Convolutional Codes Derived From Group Character Codes
Constructions of (classical) convolutional codes and their corresponding properties have been presented in the literature [1, 3–8, 12, 15–20]. In [3], the author constructed an algebraic structure for convolutional codes. Addressing the construction of maximum-distance-separable (MDS) convolutional codes (in the sense that the codes attain the generalized Singleton bound introduced in [18, Theo...
متن کاملNew Convolutional Codes Derived from Algebraic Geometry Codes
In this paper, we construct new families of convolutional codes. Such codes are obtained by means of algebraic geometry codes. Additionally, more families of convolutional codes are constructed by means of puncturing, extending, expanding and by the direct product code construction applied to algebraic geometry codes. The parameters of the new convolutional codes are better than or comparable t...
متن کاملNew convolutional codes from old convolutional codes
In this paper, starting with a family of convolutional codes, we construct a new convolutional code and we introduce also necessary and sufficient conditions in order that the new convolutional code is MDS.
متن کاملConvolutional codes from unit schemes
Algebraic methods for the construction, design and analysis of series of convolutional codes using row or block structures of unit schemes are developed. The general methods lead to the construction and analysis of series and infinite series of types of convolutional codes and of codes with specific properties. Explicit examples are given and properties may be shown algebraically. Algebraic dec...
متن کاملConvolutional Codes
The difference between block codes and convolutional codes is the encoding principle. In the block codes, the information bits are followed by the parity bits. In convolutional codes the information bits are spread along the sequence. That means that the convolutional codes map information to code bits not block wise, but sequentially convolve the sequence of information bits according to some ...
